In honour of the 15th Anniversary of 9/11, National Geographic Channel is looking back at the very best reporting we have done since this world-changing tragedy first happened using extended excerpts from past specials that relate directly to events leading up to and following the attacks on New York City and Washington DC.

Michael Moore's view on how the Bush administration allegedly used the tragic events on 9/11 to push forward its agenda for unjust wars in Afghanistan and Iraq.

ZERO: An Investigation into 9/11 has one central thesis: that the official version of the events surrounding the attacks on 9/11 cannot be true. This feature documentary explores the latest scientific evidence and reveals dramatic new witness testimony, which directly conflicts with the U.S. government's account.

On September 11, 2001, the unimaginable transpired when devastating attacks on the World Trade Center forced the shutdown of the entire U.S. airspace. Thousands of kilometres away in Gander, Newfoundland, a group of Nav Canada air traffic controllers suddenly had the lives of 33,000 people in their hands and had to think fast to find a place for them to go. Discovery uncovers how these unsung heroes managed to safely land 224 planes in four hours, without incident.

An on-the-scene documentary following the events of September 11, 2001 from an insider's view, through the lens of two French filmmakers who simply set out to make a movie about a rookie NYC fireman and ended up filming the tragic event that changed our lives forever.

A documentary examining possible historical and modern conspiracies surrounding Christianity, the 9/11 terrorist attacks, and the Federal Reserve bank.

2nd Edition of Loose Change documentary. What if...September 11th was not a surprise attack on America, but rather, a cold and calculated genocide by our own government?We were told that the twin towers were hit by commercial jetliners and subsequently brought down by jet fuel. We were told that the Pentagon was hit by a Boeing 757. We were told that flight 93 crashed in Shanksville, Pennsylvania. We were told that nineteen Arabs from halfway across the globe, acting under orders from Osama Bin Laden, were responsible. What you will see here will prove without a shadow of a doubt that everything you know about 9/11 is a complete fabrication. Conspiracy theory? It's not a theory if you can prove it.Written and narrated by Dylan Avery, this film presents a rebuttal to the official version of the September 11, 2001 terrorist attacks and the 9/11 Commission Report.

The public was not given all of the facts surrounding the worst terrorist attack in the United States of America's history.

Loose Change Final Cut is the third installment of the documentary that asks the tough questions about the 9/11 attacks and related events. This movie hopes to be the catalyst for a new independent investigation, in which the family members receive answers to their questions, and the TRUE PERPETRATORS of this horrendous crime are PROSECUTED and PUNISHED.

With the departure of the Bush Administration and the arrival of an “era of transparency,” opportunities are arising for the disclosure of new information that may shed more light on the events that took place before and after 9/11/2001. Loaded with powerful, new footage and in-depth interviews this documentary presents a wide array of evidence both known and unknown…until now.

A man with a perspective like no other on the planet. The leading structural engineer of the World Trade Center oversees its construction, haunted by its fall ever since. A guru in high-rise design. Driven by his values as a pacifist and activist and the woman engineer who emboldened, expanded and ultimately saved the man she loved. About fulfillment, fragility, and a fighting spirit.

A retrospective documentary on 9/11 in connection with the 2001 Toronto International Film Festival.
